Abstract

The invention relates to an electromagnetic actuator comprising a wire coil, an armature and a catch, wherein the armature can be moved in an actuation direction, and wherein the catch secures the armature within the electromagnetic actuator. In order to secure an armature of the electromagnetic actuator, extra parts are mounted to the electromagnetic actuator or the armature is attached via a spring. This results in bigger sizes or insufficient stopping characteristics. The present invention overcomes these disadvantages by locating a catch inside the electromagnetic actuator.
